Can one serum give better results than a pore-minimising lotion, skin brightening serum, and anti-ageing moisturiser combined?

The Effect Series Niacinamide 10% is said to deliver three benefits in one serum: pore-minimising, brightening, and anti-ageing. The question is: how does it compare to three products that individually offer each of these same benefits?

We pitted this serum against three products that have each received great reviews on its own, to see if it’s possible for one serum to be better than three products used together. Watch on to see our immediate impression of the product and how the skin fares after 1 week!
